SNA® Series
Unmatched Reliability for Your Lube Oil Applications
The Allweiler SNA® series is a three-screw pump for lubricating oil applications according to API 676 (with deviations depending on the variant), optionally with mechanical sealing according to API 682 and pressures up to 20 bar. The self-priming pump combines smooth, virtually pulsation-free flow with a wide viscosity and temperature range, as well as high efficiency and long service life. Bolted flanges and variable pump feet allow the SNA® to adapt to any system configuration. Typical applications include industrial lube oil systems such as API 614 systems for turbines, gear boxes, compressors, pumps or mining equipment.

ALLWEILER's Solutions for Mechanical Sealing
ALLWEILER's standard mechanical seal (7.20) made of high-quality carbon graphite is designed to meet common sealing requirements. As more demanding applications require additional features such as connection of additional sealing systems, leakage drainage, easier maintenance and reliability, Allweiler offers two compact cartridge seals to meet those requirements. Choose between a cartridge seal (13.5) with deviations to API 682 and a seal that meets nearly 100 % of API 682 (7.21).
Adaptable Connections for Seamless Lube Oil Integration
The versatile connection options allow you to quickly adapt to changing conditions in your lube oil system. Suction and discharge flanges are designed acc. to ASME-B 16.5 with 150/300 lbs, optionally also in other variations such as 300/300 lbs or 150/150 lbs.
By using bolted connections for suction and discharge flange instead of welded connections and flexible pump feet, the Allweiler SNA® three-screw pump becomes a plug-and-play solution for easy connection to any application.
